Rural-urban differences in use of health services before and after dementia diagnosis: a retrospective cohort study.

BACKGROUND: Rural-urban differences in health service use among persons with prevalent dementia are known. However, the extent of geographic differences in health service use over a long observation period, and prior to diagnosis, have not been sufficiently examined. The purpose of this study was to examine yearly rural-urban differences in the proportion of patients using health services, and the mean number of services, in the 5-year period before and 5-year period after a first diagnosis of dementia. METHODS: This population-based retrospective cohort study used linked administrative health data from the Canadian province of Saskatchewan to investigate the use of five health services [family physician (FP), specialist physician, hospital admission, all-type prescription drug dispensations, and short-term institutional care admission] each year from April 2008 to March 2019. Persons with dementia included 2,024 adults aged 65 years and older diagnosed from 1 April 2013 to 31 March 2014 (617 rural; 1,407 urban). Matching was performed 1:1 to persons without dementia on age group, sex, rural versus urban residence, geographic region, and comorbidity. Differences between rural and urban persons within the dementia and control cohorts were separately identified using the Z-score test for proportions (p < 0.05) and independent samples t-test for means (p < 0.05). RESULTS: Rural compared to urban persons with dementia had a lower average number of FP visits during 1-year and 2-year preindex and between 2-year and 4-year postindex (p < 0.05), a lower likelihood of at least one specialist visit and a lower average number of specialist visits during each year (p < 0.05), and a lower average number of all-type prescription drug dispensations for most of the 10-year study period (p < 0.05). Rural-urban differences were not observed in admission to hospital or short-term institutional care (p > 0.05 each year). CONCLUSIONS: This study identified important geographic differences in physician services and all-type prescription drugs before and after dementia diagnosis. Health system planners and educators must determine how to use existing resources and technological advances to support care for rural persons living with dementia.

Sleep Efficiency and Sleep Onset Latency in One Saskatchewan First Nation.

BACKGROUND: Sleep efficiency and sleep onset latency are two measures that can be used to assess sleep quality. Factors that are related to sleep quality include age, sex, sociodemographic factors, and physical and mental health status. This study examines factors related to sleep efficiency and sleep onset latency in one First Nation in Saskatchewan, Canada. METHODS: A baseline survey of the First Nations Sleep Health project was completed between 2018 and 2019 in collaboration with two Cree First Nations. One-night actigraphy evaluations were completed within one of the two First Nations. Objective actigraphy evaluations included sleep efficiency and sleep onset latency. A total of 167 individuals participated, and of these, 156 observations were available for analysis. Statistical analysis was conducted using logistic and linear regression models. RESULTS: More females (61%) than males participated in the actigraphy study, with the mean age being higher for females (39.6 years) than males (35.0 years). The mean sleep efficiency was 83.38%, and the mean sleep onset latency was 20.74 (SD = 27.25) minutes. Age, chronic pain, ever having high blood pressure, and smoking inside the house were associated with an increased risk of poor sleep efficiency in the multiple logistic regression model. Age, chronic pain, ever having anxiety, heart-related illness, and smoking inside the house were associated with longer sleep onset latency in the multiple linear regression model. CONCLUSIONS: Sleep efficiency and sleep onset latency were associated with physical and environmental factors in this First Nation.

Can Depressive Symptomatology at Diagnosis Predict Cognitive and Functional Decline Over 1 Year in Rural Canadian Patients With Dementia?

INTRODUCTION: Depressive symptomatology is often associated with the onset of dementia, although the exact form and directionality of this association is still unclear. The aim of this study is to investigate whether depressive symptomatology at the time of dementia diagnosis was predictive of cognitive, functional, and behavioral decline over 1 year. METHODS: In a Rural and Remote Memory Clinic, 375 patients consecutively diagnosed with mild cognitive impairment, Alzheimer disease, or non-Alzheimer disease dementia completed the Center for Epidemiological Studies Depression Scale at first visit and 1-year follow-up to assess depressive symptomatology. The same cohort was evaluated for cognitive, functional, and behavioral decline through the completion of 5 clinical tests performed at the first visit and at 1-year follow-up. RESULTS: Depressive symptomatology at time of dementia diagnosis did not predict cognitive or functional decline over 1 year, although increases in depressive symptomatology over 1 year significantly correlated with higher caregiver ratings of neuropsychiatric symptom severity and related distress over that time. CONCLUSION: Increasingly severe depressive symptomatology over 1 year correlated with greater caregiver distress. This study points the way for future studies delineating the relationship between depression, dementia progression, and caregiver distress.

The Contribution of Gestational Diabetes to Diabetes Risk Among First Nations and Non-First Nations Women in Saskatchewan: Results From the DIP: ORRIIGENSS Project.

OBJECTIVES: Our aim in this study was to determine the risk for diabetes mellitus (DM) among Saskatchewan First Nations (FN) and non-FN women with prior gestational DM (GDM). METHODS: Using Ministry of Health administrative databases, we conducted a retrospective cohort study of DM risk by GDM occurrence among FN and non-FN women giving birth from 1980 to 2009 and followed to March 31, 2013. We determined frequencies and odds ratios (ORs) of DM in women with/without prior GDM after stratifying by FN status, while adjusting for other DM determinants. Survival curves of women until DM diagnosis were obtained by prior GDM occurrence and stratified by ethnicity and total parity. RESULTS: De-identified data were obtained for 202,588 women. Of those who developed DM, 2,074 of 10,114 (20.5%) had previously experienced GDM (811 of 3,128 [25.9%]) FN and 1,263 of 6,986 [18.1%] non-FN). Cumulative survival of women with prior GDM until DM was higher for FN than for non-FN women (82% vs 46%), but prior GDM was a stronger predictor of DM within the non-FN cohort (prior GDM vs no GDM: OR, 9.64 for non-FN; OR, 7.05 for FN). Finally, higher total parity interacted with prior GDM to increase DM risk in both groups. With prior GDM and parity ≥3, 93% of FN and 57% of non-FN women subsequently developed DM. CONCLUSIONS: GDM is a leading determinant of T2DM among FN and non-FN women, amplified by higher parity. This contributes to earlier onset diabetes, affecting subsequent pregnancies and increasing risk for chronic diabetic complications. It may also factor into higher type 2 DM rates observed in FN women compared with men.

Trends in Work-Related Fatal Farm Injuries, Saskatchewan, Canada: 2005-2019.

OBJECTIVES: This study was conducted to estimate farm fatality rates and to describe patterns of fatal agricultural injuries on Saskatchewan farms from 2005 to 2019. METHODS: Data on work-related farm fatalities was collected from January 2005 to December 2019 in the Province of Saskatchewan as a part of the injury and mortality surveillance for the Canadian Agricultural Injury Reporting (CAIR) program. Data were abstracted from records made available by the Provincial Coroner's Office. RESULTS: There were 166 farm work-related fatalities recorded between 2005 and 2019 in Saskatchewan. The majority (93.4%) of work-related fatalities were in males. The overall work-related fatality rate was 10.5 (95% CI: 8.9-12.1) per 100,000 farm population. The overall age-adjusted work-related fatality rate was 18.1 (95% CI: 15.2-20.9) per 100,000 farm population among males and 1.4 (95% CI: 0.6-2.3) per 100,000 farm population among females. Age-adjusted rate decreased from 91.2 (95% CI: 69.4-117.66) per 100,000 farm population in 2005-2009 to 89.7 (95% CI: 64.9-120.2) per 100,000 farm population in 2015-2019 in males. Trend analysis of the work-related fatality rate in all cases showed a non-significant average annual decline of 2.6% (p = 0.156). Rollover injuries contributed to a high proportion of fatalities in children (30.0%) and the elderly population (14.9%). The most common causative agent was a tractor, and the most common location of injury was the farmyard or field. CONCLUSION: The burden of mortality in this industry is still substantial. There was a non-significant decreasing trend in the injury rate over the 15-year period. Elderly farmers continue to be at high risk for fatality, while the rates for children have declined. Application of prevention approaches could reduce the risk of fatal injury, and in particular the high proportion of rollover injuries in children and the elderly population.

Association between liver enzymes and metabolic syndrome in Canadian adults: results from the Canadian health measures survey - cycles 3 &4.

Background: The relationship between liver enzymes and Metabolic Syndrome (MetS) in different populations, including Canadians, is not consistent and well understood. We used the Canadian Health Measures Survey data (Cycles 3 and 4) to examine the cross-sectional relationships between select liver biomarkers and MetS in the adult Canadian population. The biomarkers selected were gamma-glutamyl transferase (GGT), aspartate aminotransferase (AST), and alkaline phosphatase (ALKP). Methods: Fasting blood samples (FBS) were collected from adults above the age of 20 years for Cycle 3 and Cycle 4 (n = 3003). MetS was diagnosed if the subjects had three or more risk determinants according to the Joint Interim Statement criteria. Primary risk factors included quartile cut-offs for each of the biomarkers ALKP, AST, GGT for males and females separately. A multivariable logistic regression technique based on a maximum likelihood approach was used to evaluate the association between quartiles of ALKP, AST, and GGT, other individual and contextual factors, and the prevalence of MetS. Results: MetS was prevalent in 32.3% of subjects. BMI was an effect modifier in the relationship between GGT and MetS prevalence, while sex was an effect modifier in the relationship between ALKP and MetS prevalence; and age was an effect modifier in the relationship between AST and MetS prevalence. Conclusions: Since the mechanisms to underpin the associations between the liver enzymes activity and MetS are unknown, further epidemiologic investigations using longitudinal designs are necessary to understand these associations.

STOP-Bang Score and Prediction of Severity of Obstructive Sleep Apnea in a First Nation Community in Saskatchewan, Canada.

The STOP-Bang questionnaire is an easy-to-administer scoring model to screen and identify patients at high risk of obstructive sleep apnea (OSA). However, its diagnostic utility has never been tested with First Nation peoples. The objective was to determine the predictive parameters and the utility of the STOP-Bang questionnaire as an OSA screening tool in a First Nation community in Saskatchewan. The baseline survey of the First Nations Sleep Health Project (FNSHP) was completed between 2018 and 2019. Of the available 233 sleep apnea tests, 215 participants completed the STOP-Bang score questionnaire. A proportional odds ordinal logistic regression analysis was conducted using the total score of the STOP-Bang as the independent variable with equal weight given to each response. Predicted probabilities for each score at cut-off points of the Apnea Hypopnea Index (AHI) were calculated and plotted. To assess the performance of the STOP-Bang questionnaire, sensitivity, specificity, positive predictive values (PPVs), negative predictive values (NPVs), and area under the curve (AUC) were calculated. These data suggest that a STOP-Bang score ≥ 5 will allow healthcare professionals to identify individuals with an increased probability of moderate-to-severe OSA, with high specificity (93.7%) and NPV (91.8%). For the STOP-Bang score cut-off ≥ 3, the sensitivity was 53.1% for all OSA and 72.0% for moderate-to-severe OSA. For the STOP-Bang score cut-off ≥ 3, the specificity was 68.4% for all OSA and 62.6% for moderate-to-severe OSA. The STOP-Bang score was modestly superior to the symptom of loud snoring, or loud snoring plus obesity in this population. Analysis by sex suggested that a STOP-Bang score ≥ 5 was able to identify individuals with increased probability of moderate-to-severe OSA, for males with acceptable diagnostic test accuracy for detecting participants with OSA, but there was no diagnostic test accuracy for females.

Obesity, Sex, Snoring and Severity of OSA in a First Nation Community in Saskatchewan, Canada.

Sleep disorders have been related to body weight, social conditions, and a number of comorbidities. These include high blood pressure and type 2 diabetes, both of which are prevalent in the First Nations communities. We explored relationships between obstructive sleep apnea (OSA) and risk factors including social, environmental, and individual circumstances. An interviewer-administered survey was conducted with adult participants in 2018−2019 in a First Nations community in Saskatchewan, Canada. The survey collected information on demographic variables, individual and contextual determinants of sleep health, and objective clinical measurements. The presence of OSA was defined as an apnea−hypopnea index (AHI) ≥5. Multiple ordinal logistic regression analysis was conducted to examine relationships between the severity of OSA and potential risk factors. In addition to the survey, 233 men and women participated in a Level 3 one-night home sleep test. Of those, 105 (45.1%) participants were reported to have obstructive sleep apnea (AHI ≥ 5). Mild and moderately severe OSA (AHI ≥ 5 to <30) was present in 39.9% and severe OSA (AHI ≥ 30) was identified in 5.2% of participants. Being male, being obese, and snoring loudly were significantly associated with severity of OSA. The severity of OSA in one First Nation appears relatively common and may be related to mainly individual factors such as loud snoring, obesity, and sex.

Housing inadequacy in rural Saskatchewan First Nation communities.

Housing and house conditions on First Nation communities in Canada are important determinants of health for community members. Little is known about rural First Nation housing in the Canadian Prairies. The aim was to survey houses in two rural First Nation communities in Saskatchewan, Canada to understand housing conditions, prevalence of mold/mildew and dampness, and sources, locations and frequency of mold and dampness. Surveys were conducted with an adult member of each household in 144 houses. Surveys assessed: size, age, and number of rooms in the house; number of individuals residing in the house; presence of mold/mildew and dampness, and sources, locations and frequency of mold and dampness. Houses were mostly two-bedrooms (25.7%) or more (67.4%). Thirty-one percent of houses had six or more people living in the house with crowding present in 68.8% of houses. Almost half of the houses (44.5%) were in need of major repairs. More than half of the houses had water or dampness in the past 12 months in which dripping/puddles and standing water were most commonly identified and were from surface water and plumbing. More than half of the houses indicated that this dampness caused damage. A smell of mold or mildew was present in over half of the houses (52.1%) and 73.3% of these houses indicated that this smell was always present. Housing adequacy including crowding, dampness, and mold are significant issues for houses in these two rural Saskatchewan First Nation communities. Housing inadequacy is more common in these rural communities as compared to Canadian statistics. Housing inadequacy is modifiable and is important to address for multiple reasons, but notably, as a social determinant of health. Federal government strategy to address and redress housing in First Nation communities in Canada is a fiduciary responsibility and critical to reconciliation.

What Happens to the Worried Well? Follow-Up of Subjective Cognitive Impairment.

BACKGROUND: Increasing concern around perceived neurocognitive decline is increasing the number of referrals to specialists and anxiety for patients. We aimed to explore the likelihood of the "worried well" experiencing neurocognitive decline and developing a neurological diagnosis. METHODS: A total of 166 "worried well" patients who attended the Rural and Remote Memory Clinic (RRMC) between 2004 and 2019 were included in this study. Demographic, health, social, and behavioral factors were measured at the initial visit. Mini-Mental State Examination (MMSE), Center for Epidemiologic Studies Depression Scale (CESD), and Functional Activities Questionnaire (FAQ) scores were measured and compared at initial assessment and at 1-year follow-up. MMSE scores over time were assessed with a mean follow-up of 2.95 years (SD 2.87). RESULTS: No statistically significant difference was seen in MMSE, CESD, or FAQ scores when comparing clinic day to 1-year follow-up, and no consistent pattern of MMSE score over time was seen. Of the 166 patients with subjective cognitive impairment (SCI) on initial assessment, 5 were diagnosed with Alzheimer's disease (AD) at 8.5, 3.5, 5, 3, and 1.75 years; 2 were diagnosed with MCI at 1 and 2 years; 1 was diagnosed with vascular cognitive impairment at 5 years; and 1 was diagnosed with frontotemporal dementia (FTD) at 0.5 years. CONCLUSION: The likelihood of a patient with SCI developing a neurological diagnosis is reassuringly low (9/166), but not irrelevant. This, along with the benefits of early diagnosis and treatment for dementia, leads us to believe that patients with SCI should still be seen in follow-up at least at the 1-year mark.

Duration and quality of sleep in 2 rural Cree First Nation communities in Saskatchewan, Canada.

STUDY OBJECTIVES: Estimates of sleep duration and quality are lacking for Canadian First Nations peoples. This study examines the prevalence of and risk factors for short/normal/long sleep duration and sleep quality. METHODS: Five hundred eighty-eight adults participated in the baseline survey of the First Nations Sleep Health Project conducted in 2018-2019 in Saskatchewan, Canada. Sleep duration and quality were self-reported. RESULTS: Mean sleep duration was 8.18 hours per night. About 45.5% slept the recommended 7 hours per night. However, short sleep duration and poor sleep quality were relatively common: about one-quarter of the participants slept fewer hours than recommended. Sleep duration was significantly less for men than women. Women were significantly more likely to report poor sleep quality than males. Multiple regression models revealed that age was significantly related with shorter sleep duration; sex and employment status were significantly related with sleep duration; and sex and income indicators were significantly associated with sleep quality. Nearly half of participants reported having had the recommended hours of sleep, but nearly two-thirds reported poor sleep quality. CONCLUSIONS: Information about the proportion of First Nations adults who sleep the recommended duration and the quality of sleep is important in informing health care and health policy.

Predictive biomarkers of cardiovascular disease in adult Canadian population.

BACKGROUND: Elevated levels of the enzymes gamma-glutamyltransferase (GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and C-reactive protein (CRP) have been shown to be associated with increased risk of cardiovascular disease (CVD). Objective: To assess cross-sectional relationships between biomarkers GGT, ALT, AST, ALP and CVD in adult Canadian population. METHODS: The Canadian Health Measures Surveys (CHMSs) are a series of cross-sectional national surveys and collect information on indicators of general health and wellness of Canadians. The CHMS has four components. We used data from the first three components (for Study participants ≥ 20 years) from CHMS cycles 1 through 5. RESULTS: Multivariable logistic regression revealed: immigration status [Odds ratio (OR)(95% Confidence Interval (95% CI)) = 0.67 (0.53-0.85), reference category (RC)-no-immigrant] education [1.38(1.10-1.75), RC- > secondary education]; smoking status [ex-smokers: 1.16(0.89-1.51); current smokers: 1.41(0.98-2.05), RC-non-smoker]; and income [middle income: 0.69(0.43-1.10); high income: 0.49(0.29-0.83); RC-lower income] were significantly associated with CVD prevalence. CONCLUSION: The relationship of GGT with CVD prevalence changed among age groups and body mass index categories; was different for males and females; and diabetes was an effect modifier in the relationship between AST and CVD prevalence. Socio-economic factors were significantly associated with CVD prevalence.

Seasonal Changes in Sleep Patterns in Two Saskatchewan First Nation Communities.

Sleep is crucial for maintaining the recovery and restoration of the body and brain. Less sleep is associated with poor mental and physical performance. Seasonal changes in sleep patterns can be observed. This paper examines seasonal effects on sleep timing, duration, and problems in two Cree First Nation communities in Saskatchewan, Canada. Data were available from a community survey of 588 adults aged 18 years and older (range: 18-78 years) with 44.2% males and 55.8% females. Results are presented using descriptive statistics and a binary logistic-regression model to identify the association between seasonal changes in sleep patterns, and demographic, social, and environmental factors. The participants reported sleeping the least during the spring and summer months and sleeping the most during the fall and winter months. This was further confirmed by sleep hours and the lower proportion of recommended hours of sleep during the spring and summer, and a higher proportion of longer sleep duration during the fall and winter months. There was no significant variation in sleeping onset and wake-up times by season. Overall, there were no significant differences in the prevalence of sleep deprivation, insomnia, and excessive daytime sleepiness by season. When stratified by age group and sex, some differences existed in the prevalence of sleep problems by season. More than two-thirds (68.6%) of the participants reported that there was a change in sleep patterns across seasons, and about 26.0% reported a very or extremely marked change in sleep patterns across seasons. Changes in sleep patterns by season were related to money left at the end of the month and damage caused by dampness in the house.

Sleep deprivation in two Saskatchewan First Nation communities: a public health consideration.

OBJECTIVES: Sleep deprivation is a common problem in Canada and is associated with many health problems. More than a quarter of Canadians get fewer than the recommended sleep hours (<7 h). This paper examines the prevalence and risk factors for sleep deprivation in two First Nation communities in Saskatchewan, Canada. METHODS: The baseline cross-sectional survey was completed between 2018 and 2019 in collaboration with the two Cree First Nation communities in Saskatchewan, Canada. There were five hundred and eighty-eight participants participated in the survey from two communities. A Multivariate logistic regression model was used for analysis. RESULTS: The prevalence of sleep deprivation (<7 h of sleep) was 25.4%. The multivariate logistics regression revealed that middle and older age groups, visible mold in the house, and being male with nighttime insomnia symptoms were significantly associated with a higher risk of sleep deprivation among study participants in the study. CONCLUSIONS: In these two First Nation communities, a higher proportion of the participants reported having sleep deprivation. This was a unique study, which evolved from ongoing research collaboration with two First Nation communities in Saskatchewan, Canada. Findings will be helpful in the management of patients with sleep deprivation in these communities; as well as for co-creating policy with the communities and future research priorities.

Associations between Housing Factors and Respiratory Symptoms in Two Saskatchewan First Nations Communities.

Inadequate housing is commonplace in First Nations in Canada, often leading to environmental impacts on housing such as dampness and mold. First Nations communities suffer from a higher prevalence of respiratory-related health conditions than the general Canadian population. There is limited Canadian literature evaluating the relationship between housing factors and the respiratory health of adults within First Nations communities. This study was undertaken with two Saskatchewan First Nations communities. The study population consisted of 293 individuals within 131 households. The individuals completed questionnaires on their general and respiratory health, and one member of each household completed a household questionnaire. The collection of environmental samples from within the house was undertaken. The respiratory outcomes of interest focused on the individuals with ever wheeze, reported by 77.8% of the individuals, and shortness of breath, reported by 52.6% of the individuals. Body mass index, the nontraditional use of tobacco (i.e., current and ex-smoking), the nontraditional use of tobacco in the house (i.e., smoking in the house), dampness in the house in the last 12 months, and always having a smell of mold in the house were significantly associated with respiratory symptoms. The results reveal that respiratory symptom rates were high in the population and housing factors were significantly associated with respiratory symptoms. Addressing and redressing housing inadequacies in First Nations communities are important in preventing additional burdens to health.

Prevalence of Hormone-Related Cancers (HRCs) at Two-Time Points in Rural Saskatchewan: The Saskatchewan Rural Health Study (SRHS).

OBJECTIVE: This study aimed to determine the prevalence of hormone-related cancers (HRCs) among Saskatchewan rural dwellers and explore associated risk factors. METHODS: Data were analyzed from the Saskatchewan Rural Health Study (SRHS), which was a prospective cohort (2010 to 2014). Completed questionnaires were obtained from 4624 (2797) households, with information about 8261 (4867) individuals more than or equal to 18 years at baseline (follow-up). The crude prevalence of HRCs was calculated using appropriate formulae. Adjusted prevalence was calculated using logistic regression based on the generalized estimating equation (GEE). RESULTS: Crude prevalence of HRCs was 3.0% at the baseline. Variables significantly associated with HRCs were: exposure to radiation comprising ultraviolet radiation from sunlight as well as ionizing radiation (odds ratio [OR] 3.39; 95% confidence interval [CI]: 2.23, 4.84), previous history of cancer in sibling (OR = 1.51, 95% CI: 1.11, 2.07) and in father (OR = 1.37; 95% CI = 1.01, 1.86). CONCLUSIONS: The study informs the Saskatchewan Health Region for health care resource allocation.

Prevalence of Insomnia in Two Saskatchewan First Nation Communities.

Insomnia is a common problem in Canada and has been associated with increased use of health care services and economic burden. This paper examines the prevalence and risk factors for insomnia in two Cree First Nation communities in Saskatchewan, Canada. Five hundred and eighty-eight adults participated in a baseline survey conducted as part of the First Nations Sleep Health Collaborative Project. The prevalence of insomnia was 19.2% among participants with an Insomnia Severity Index score of ≥15. Following the definition of nighttime insomnia symptoms, however, the prevalence of insomnia was much higher, at 32.6%. Multivariate logistic regression modeling revealed that age, physical health, depression diagnosis, chronic pain, prescription medication use for any health condition, and waking up during the night due to terrifying dreams, nightmares, or flashbacks related to traumatic events were risk factors for insomnia among participants from two Saskatchewan Cree First Nation communities.

Congenital Anomalies of the Kidney and Urinary Tract (CAKUT): An Emerging Relationship With Pregestational Diabetes Mellitus Among First Nations and Non-First Nations People in Saskatchewan-Results From the DIP: ORRIIGENSS Project.

OBJECTIVES: Because congenital anomalies of the kidneys and urinary tract (CAKUT) represent a frequent cause of end stage renal disease (ESRD) in the young, we explored the epidemiology of CAKUT and the role of diabetes in pregnancy. METHODS: This was a retrospective cohort study of CAKUT, by maternal diabetes status, from among all 1980‒2009 births in Saskatchewan First Nations (FN) and non-First Nations (non-FN) people. We determined frequencies, predictors and complications of CAKUT, as well as cumulative survival (to 2014) of affected persons until ESRD and death. RESULTS: Of the 411,055 babies (204,167 mothers) in the Saskatchewan maternal-infant database, 2,540 had CAKUT (391 FN and 2,149 non-FN). Overall annual CAKUT incidence was 0.63% for non-FN and 0.57% for FN (p=0.082), but 5-year CAKUT incidence only increased among FN (0.40% in 1980‒1984 and 0.76% in 2005‒2009, p<0.0001) and was highest among offspring of FN mothers with pregestational diabetes (pre-G/DM) (0% before 1995, 2.51% in 2000‒2004 and 1.66% in 2005-2009). Pre-G/DM, but not gestational diabetes mellitus (GDM), was an independent predictor of CAKUT in non-FN (odds ratio, 1.79; 95% confidence interval, 1.20 to 2.69), and in FN interacting with maternal history of stillbirth (odds ratio, 7.90; 95% confidence interval, 1.14 to 54.6). ESRD was >100-fold more likely among offspring with CAKUT compared with all other offspring and was responsible for 40% of ESRD cases in young FN and non-FN people. CONCLUSIONS: In Saskatchewan, pre-G/DM is an emerging cause of CAKUT, accounting for 40% of ESRD cases in FN/non-FN children and young adults. Because pre-G/DM‒related CAKUT is potentially preventable with optimal glycemic management, increased recognition of this serious complication is required.

The importance of organizational commitment in rural nurses' intent to leave.

AIMS: To examine determinants of intention to leave a nursing position in rural and remote areas within the next year, for Registered Nurses or Nurse Practitioners (RNs/NPs) and Licensed Practical Nurses (LPNs). DESIGN: A pan-Canadian cross-sectional survey. METHODS: The Nursing Practice in Rural and Remote Canada II survey (2014-2015) used stratified, systematic sampling and obtained two samples of questionnaire responses on intent to leave from 1,932 RNs/NPs and 1,133 LPNs. Separate logistic regression analyses were conducted for RNs/NPs and LPNs. RESULTS: For RNs/NPs, 19.8% of the variance on intent to leave was explained by 11 variables; and for LPNs, 16.9% of the variance was explained by seven variables. Organizational commitment was the only variable associated with intent to leave for both RNs/NPs and LPNs. CONCLUSIONS: Enhancement of organizational commitment is important in reducing intent to leave and turnover. Since most variables associated with intent to leave differ between RNs/NPs and LPNs, the distinction of nurse type is critical for the development of rural-specific turnover reduction strategies. Comparison of determinants of intent to leave in the current RNs/NPs analysis with the first pan-Canadian study of rural and remote nurses (2001-2002) showed similarity of issues for RNs/NPs over time, suggesting that some issues addressing turnover remain unresolved. IMPACT: The geographic maldistribution of nurses requires focused attention on nurses' intent to leave. This research shows that healthcare organizations would do well to develop policies targeting specific variables associated with intent to leave for each type of nurse in the rural and remote context. Practical strategies could include specific continuing education initiatives, tailored mentoring programs, and the creation of career pathways for nurses in rural and remote settings. They would also include place-based actions designed to enhance nurses' integration with their communities and which would be planned together with communities and nurses themselves.

Longitudinal Changes in Prevalence of Colorectal Cancer in Farm and Non-Farm Residents of Saskatchewan.

OBJECTIVE: To determine predictors associated with longitudinal changes in colorectal cancer (CRC) prevalence in farm and non-farm rural residents in Saskatchewan, Canada. METHODS: Data from the Saskatchewan Rural Health Study were collected from 8261 individuals nested within 4624 households at baseline survey in 2010 and 4867 individuals (2797 households) at follow-up survey in 2014. The study sample consists of 5599 individuals (baseline) and 3933 at (follow-up) (more than or equal to 50 years). RESULTS: The prevalence of CRC increased over time among rural farm (baseline: 0.8%; follow-up: 1.3%, P < 0.05) and non-farm (baseline: 1.4%; follow-up: 2.0%, P > 0.05) residents. Longitudinal predictors of CRC prevalence were: quadrant, location of home, mother ever had cancer, age, body mass index (BMI), sex, radiation, natural gas. CONCLUSIONS: Longitudinal changes in prevalence of CRC among farm and non-farm residents appear to depend on a complex combination of individual and contextual factors.
